Focus on getting it driving first. You may find there is somewhere better to put that money!

Great results! It must really scoot 
Do you feel the drivability is not as good with the bigger turbo? Very curious if its too much sacrifice!

Awesome! How is the transient response in comparison to the T3?

Awesome, that seems like it will be a good fit. The 56mm would probably be too big and be sluggish.

.83A/R T4 twinscroll housing. Did you make a new manifold or just adapt to a T4 flange and keep it open collector?
Which compressor did you go with? 56mm or 51mm?
Curious because I have been dreaming of a similar setup on my car. Also curious how it compared to the ford T3 60trim. Ive been concerned the S200sx is too large of a turbine.
The N55 turbocharger is essentially an S100 turbine with an EFR 62mm wheel ans smaller inducer. I think that would be an awesome turbo!

What turbo were you using again? From the turbine measurements it looked like a GT30 turbine with a nissan cover? Hard to tell since just about anything has a 2 bolt cover option.
Which S200 are you going with? Which turbine housing?

Engine management / Re: M42 ECU pinouts
« on: March 25, 2018, 01:42:28 PM »
It is/was the images for the E30/E36 from the E36 Bentley manual. They are the same pinouts minus the DSIA valve and possibly other features the E30 M42 did not have.

That turbo is more designed for a snowmobile/atv/motorcycle engine. Its way too small for your engine. A GT25 frame turbo is the smallest I would consider, GT28 is more appropriate.

Swaps, Turbos, Buildups / Re: M42 DASC limits
« on: August 20, 2017, 08:11:03 PM »
It depends on how the tuning is done. With the FMU/RRFPR you are more limited as you dont have precise control over the injectors. If Mark D tunes the car for larger injectors you should be able to get a better idea of the power capability of the fuel system.
Your main limitation is maximum torque with the factory rods. The stock DASC kit still leaves a lot of room to grow. I think the main limitation will be how small of a pulley diameter you can run before the Eaton is out of the efficiency range and IATs start climbing.

Engine + Driveline / Re: To turbo or not
« on: April 27, 2017, 05:04:41 PM »
Jakes kit is a good way to get you up and running with minimal issues. Over time you can easily upgrade parts to make improvements. The kit will provide plenty of oomph to keep you happy for a while.
Biggest room for improvement with the kit would be a standalone engine ECU. There are plenty of people here who can help you with learning to tune
Another "bolt on" option is the DASC roots supercharger kit. They come up for sale fairly frequently.

Engine + Driveline / Re: AFM or not to AFM, that is the question
« on: April 27, 2017, 04:56:58 PM »
Can you read the ICV position/duty cycle with the service tool? If so make sure that is rational. Also make sure OAT (outside air temp), IAT (inlet air temp), ECT (engine coolant temp), baro, ect all read rational. If one of these is off it can significantly impact your fueling which will cause stalling/bogging.
Other place I would look is for air leaks after the AFM. Best way to use this is use propane or similar around all the joints/gaskets. If you have a leak it will ingest the propane and rev up.
Check your intake elbow and intake manifold gaskets for common air leak paths
